Taiwan's legalization of same-sex marriage affords legal status for romantic relationships between sexual minority individuals. Yet, little is known about the role of intimate relationships in the experiences of minority stress and mental health among gay men. This study tested a model where internalized homophobia mediated the association between distal minority stress and depressive symptoms and relationship satisfaction was posited as a moderator. Data came from a sample (n = 557) of Taiwanese young gay men who were in a romantic relationship. Respondents completed the scales of distal minority stress, internalized homophobia, relationship satisfaction, and depressive symptoms. Mediation and moderation analyses were performed on the macro PROCESS. The Johnson-Neyman (J-N) technique was used to interpret the moderating effect of relationship satisfaction. Results show that both distal minority stress and internalized homophobia were positively associated with depressive symptoms. Internalized homophobia partially mediated the association between distal minority stress and depressive symptoms. Relationship satisfaction had a moderating effect. The effect of distal minority stress was lower among those who reported high satisfaction in their current romantic relationship. This study suggested that a satisfying relationship provides protection for gay men's mental health. Clinicians should attend to relationship issues when working with sexual minority clients.In its current mode of identification of scientific publications, the digital object identifier (DOI) is not more than a web linking of published material to their publishing sources. When a given DOI is searched in the DOI website (doi.org), we are redirected to the publishing websites, if the material is available, or an error message (Not Found) will appear if the DOI-associated content is not available or has moved to a new location. To bestow a worthwhile value to DOI assignations, I suggest the establishment of a unique persistent DOI database (for e.g., as a DOI hub, DOI library, or DOI indexer) in which all the DOI assigned by publishers and journals will be listed in one and same place with basics bibliographic metadata and complete citation information, including the DOI link itself, authors' names, manuscripts' titles, publishing source, date of publication, and ideally abstracts if available. As a result, when a DOI is searched in the DOI hub, full bibliographic information should be retrievable regardless of its status in the publishing source. Basic indexation information and metadata associated with published articles will be always accessible and findable independently from the publishing sources. A unique, general and long-term preserved DOI hub will make it easy to search, find and cite scientific literature from the various scientific fields even if a journal or publisher ceases its publishing activity.Arginine kinase from Trypanosoma cruzi (TcAK) catalyzes the interconversion of arginine and phosphoarginine to maintain the ATP/ADP cell balance, and is involved in the parasites' energetic homeostasis and stress responses. Using virtual screening approaches, some plant-derived polyphenolic pigments, such as anthocyanidins, were predicted to inhibit TcAK activity. Here, it was demonstrated that the anthocyanidin delphinidin showed a non-competitive inhibition mechanism of TcAK (Ki arginine = 1.32??M and Ki ATP = 500??M). Molecular docking simulations predicted that delphinidin occupies part of the ATP/ADP pocket, more specifically the one that binds the ribose phosphate, and molecular dynamics simulations confirmed the amino acids involved in binding. Delphinidin exerted trypanocidal activity over T. cruzi trypomastigotes with a calculated IC50 of 19.51??M. Anthocyanidins are low-toxicity natural products which can be exploited for the development of trypanocidal drugs with less secondary effects than those currently used for the treatment of Chagas disease.Gliomas are relatively common tumors in aged dogs (especially brachycephalic breeds), and the dog is proving to be useful as a translational model for humans with brain tumors. Hitherto, there is relatively little prognostic data for canine gliomas and none on outcome related to specific histological features. Histologic sections of tumor biopsies from 33 dogs with glioma treated with surgical resection and immunotherapy and 21 whole brains obtained postmortem were reviewed. Tumors were diagnosed as astrocytic, oligodendroglial, or undefined glioma using Comparative Brain Tumor Consortium criteria. Putative features of malignancy were evaluated, namely, mitotic counts, glomeruloid vascularization, and necrosis. For biopsies, dogs with astrocytic tumors lived longer than those with oligodendroglial or undefined tumor types (median survival 743, 205, and 144 days, respectively). Dogs with low-grade gliomas lived longer than those with high-grade gliomas (median survival 734 and 194 days, respectively). Based on analysis of tumor biopsies, low mitotic counts, absence of glomeruloid vascularization, and absence of necrosis correlated with increased survival (median 293, 223, and 220 days, respectively), whereas high mitotic counts, glomeruloid vascularization, and necrosis correlated with poor survival (median 190, 170, and 154 days, respectively). Mitotic count was the only histological feature in biopsy samples that significantly correlated with survival (P less then .05). Whole-brain analyses for those same histologic features had similar and more robust correlations, and were statistically significant for all features (P less then .05). The small size of biopsy samples may explain differences between biopsy and whole-brain tumor data. These findings will allow more accurate prognosis for gliomas.Prostate cancer treatments disrupt receptive anal intercourse (RAI) for gay and bisexual men (GBM). Sexual dysfunction following prostate cancer treatment may include severe pain in the anorectum during RAI (i.e., anodyspareunia). https://www.selleckchem.com/products/LY2228820.html The purpose of this study was to explore the impact of prostate cancer and its treatments on RAI among GBM. Data were from a cross-sectional online survey of 100 GBM prostate cancer survivors who reported pleasurable RAI prior to treatment. Approximately 47% of the sample reported recent RAI, which was more common among GBM in long-term relationships. RAI was also associated with engagement in other sexual behaviors (e.g., oral and insertive anal sex). Anodyspareunia was reported by 23% of the men who had attempted recent RAI. Anodyspareunia was negatively associated with mental health, performing oral sex on a partner, and bowel function. The overwhelming majority received no information from their healthcare providers about loss of RAI function prior to prostate cancer treatment. Culturally responsive cancer survivorship care may need to address the loss of RAI function for GBM prostate cancer survivors.
